I have a 36 cal home made rifle and I shoot 15 gr by volume of 777 with a musket cap and it shoots great with little or no fouling . I am not shure if they make 777 in 3f size like pordx p ,something to think about . A friend that has a older TC 32 uses 10-12 gr of 3f with good results . Last year the score was ,for me 32 squirles with 42 shots and for him 47 squirles with 61 shots (he gets to hunt more) have fun with the smoke pole.
